    • An apparatus, system, and method are disclosed for adjusting trace data granularity. An initialization module sets a base granularity for trace data recorded for a component. A registration module registers a condition counter comprising a condition set. The threshold module sets a count threshold for the condition counter. An increment module counts each instance of the condition set. An adjustment module adjusts the granularity of trace data stored for the component to a modified granularity if the condition count exceeds the count threshold. In one embodiment, a timer module times an adjusted trace data granularity time interval. The adjustment module may set the granularity of the trace data to the base granularity when the adjusted trace data granularity time interval exceeds a specified time interval.
    • 公开了一种用于调整跟踪数据粒度的装置,系统和方法。 初始化模块为记录的组件的跟踪数据设置基本粒度。 注册模块注册包括条件集的条件计数器。 阈值模块设置条件计数器的计数阈值。 增量模块对条件集的每个实例进行计数。 如果条件数超过计数阈值,则调整模块将存储在组件中的跟踪数据的粒度调整为修改的粒度。 在一个实施例中,定时器模块对经调整的跟踪数据粒度时间间隔进行乘法。 当调整的跟踪数据粒度时间间隔超过指定的时间间隔时,调整模块可以将跟踪数据的粒度设置为基本粒度。

    • An apparatus, method, and system associates an identifier with a data packet. The identifier uniquely identifies a communication module, such as a host interface card, within a data storage system. In operation, a computer host sends a data packet to a server. The communication module receives the data packet and associates an identifier, unique to the communication module, with the data packet. The data packet is stored in a disk array, such as a Redundant Array of Independent Disks (RAID) system. When the computer host later requests the stored data packet, a validation module, which may be implemented within a PCI adapter such as a host interface card, retrieves the data packet and determines whether the data packet is corrupt. If the data packet is corrupt, the validation module identifies which host interface card corrupted the data with the use of the unique identifier associated with the data packet. The faulty communication module may then be removed from operation in the data storage system.
    • 设备,方法和系统将标识符与数据分组相关联。 标识符唯一地标识数据存储系统内的通信模块,例如主机接口卡。 在操作中,计算机主机向服务器发送数据包。 通信模块接收数据分组并将通信模块唯一的标识符与数据分组相关联。 数据包存储在磁盘阵列中,例如独立磁盘冗余阵列(RAID)系统。 当计算机主机稍后请求存储的数据分组时,可以在PCI适配器(例如主机接口卡)内实现的验证模块检索数据分组并确定数据分组是否损坏。 如果数据包损坏,则验证模块使用与数据包相关联的唯一标识符来识别哪个主机接口卡损坏了数据。 然后,故障通信模块可以从数据存储系统中的操作中移除。

    • A method for initiating a data storage facility recovery process in a data processing system having a first peer data storage facility and a second peer data storage facility communicating with the first peer data storage facility by a communication link. The method of initiating a recovery process is invoked by one peer data storage facility upon another peer data storage facility operating under a peer to peer remote copy (PPRC) protocol. Data copied from a first peer data storage facility to a second peer data storage facility is monitored for errors. Upon detection of an error by one peer data storage facility, recovery and data collection operations are initiated on the other peer data storage facility. Preferably, the initiation of recovery and data collection operations occurs out of band, over a second communication link between the peer data storage facilities.
    • 一种用于在具有通过通信链路与第一对等数据存储设备通信的第一对等数据存储设施和第二对等数据存储设备的数据处理系统中启动数据存储设备恢复过程的方法。 启动恢复过程的方法由一个对等数据存储设施调用于在对等远程复制(PPRC)协议下操作的另一个对等数据存储设备。 监视从第一对等数据存储设施复制到第二对等数据存储设施的数据以获得错误。 在通过一个对等数据存储设备检测到错误时,恢复和数据收集操作在另一个对等数据存储设备上启动。 优选地,通过对等数据存储设施之间的第二通信链路,恢复和数据收集操作的发起在带外发生。

    • In one embodiment, a drop detection method includes: moving a light source along a first side of the drop zone to illuminate drops passing through a drop zone; and, without blocking any part of the drop zone, detecting light scattered off the drops as the drops pass through the drop zone. In another embodiment, a drop detector includes: a light source on a first side of the drop zone for illuminating drops passing through a drop zone; a light detector on the first side of the drop zone near the light source and a movable carriage carrying the light source and the light detector. The light detector is exposed to the drop zone for detecting light scattered off drops as the drops pass through the drop zone. The carriage is movable along the first side of the drop zone in a direction transverse to the drop direction.
